CITY OF SHAKOPEE Memorandum TO: Mayor & City Council Mark McNeill, City Administrator FROM: Bruce Loney, Public Works Director SUBJECT: Acceptance of Feasibility Report for CSAH 83 Trunk Sanitary Sewer Extension, from Church Addition to Valley View Road, Project No. 2006-6 DATE: February 7,2006 INTRODUCTION: Attached to this memorandum is Resolution No. 6363, a resolution accepting the feasibility report and establishing a public hearing date for March 7, 2006 for the CSAH 83 Trunk Sanitary Sewer Extension, from the Church Addition to Valley View Road. Also attached is Resolution No. 6365, a resolution authorizing eminent domain proceedings. BACKGROUND: On January 17, 2006, City Council adopted Resolution No. 6361, a resolution ordering the preparation of a report for the CSAH 83 Trunk Sanitary Sewer Extension, from the Church Addition to Valley View Road. The City also authorized an extension agreement with WSB & Associates, Inc. to prepare the feasibility report. Attached is the feasibility report outlining the project costs, project funding, easement acquisition and lateral sewer connection charge associated with this trunk sanitary sewer extension. This project will provide a sewer service to the area west of CSAH 83 and south of Church Addition known as the Southwest Shakopee District. The trunk sewer extension does provide lateral sewer benefit to parcels adj acent to the trunk sewer location. Also, extending this sewer will eliminate a lift station in the River Valley Estates 2nd Addition. Associated with this project and the feasibility report, is a need to acquire additional easements from property owners along CSAH 83. Staff is requesting authorization for eminent domain proceedings in order to obtain the right-of-way to meet the proposed project schedule. If the project is not approved at the March 7,2006 public hearing, staff would not proceed with filing a petition for condemnation of the easements. It has been proposed by Pulte Homes, Inc., the developer of River Valley Estates that they would contribute $150,000.00 towards the City's trunk expenditures and an additional $90,000.00 for the lift station not having to be constructed if the sewer is in operation by September, 2006. In order to meet the time line of September, 2006, an authorization for eminent domain proceedings needs to be done at the February 7,2006 Council meeting. Lateral sewer to developing properties can be assessed or a lateral sewer connection charge determined for each trunk sewer project. For this project, a lateral sewer connection charge is recommended. The reason for this recommendation is that the properties adjacent to CSAH 83 sewer are not proposed to develop at this time and an assessment on the property might cause theneed to develop. ALTERNATIVES: 1. Adopt Resolution No. 6363, a resolution accepting the feasibility report and establishing a public hearing for March 7,2006 for the CSAH 83 Trunk Sanitary Sewer Extension, from the Church Addition to Valley View Road. 2. Adopt Resolution No. 6365, a resolution authorizing eminent domain proceedings for the Trunk Sanitary Sewer. Extension Project. 3. Do not approve these resolutions at this time. 4. Table for additional information. RECOMMENDATION: Staff would recommend Alternative No.1 and No.2 in order to proceed with this project, to provide a gravity sanitary sewer service to River Valley Estates and other areas beyond and in order to have a public hearing on March 7,2006.

I I I I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shako pee, MN WSB Project No. 1281-96 I I 1. INTRODUCTION On January 17,2006, the City of Shakopee ordered the preparation of a feasibility report to be I prepared by WSB & Associates, Inc. for a trunk sanitary sewer extension from the Church Addition to Valley View Road, City Project No. 2006-6. I 2. SCOPE Thisreport addresses the anticipated project costs and feasibility of extending a trunk sanitary I sewer from the Church Addition approximately 4,000 feet south along CSAH 83 to Valley View Road. See Figure 1 in the Appendix for a project location map. I 3. BACKGROUND The existing sanitary sewer line from the Church Addition is proposed to be extended along I CSAH 83 to provide trunk sanitary sewer to undeveloped properties in the southwest area of the City of Shakopee that currently do not have sanitary sewer. The proposed areas to be served are identified in the City of Shakopee's Comprehensive Sanitary Sewer Plan asSub-Districts: SS-C, I SS-E; SW-A, SW-B, SW-C, and SW-D. To extend the trunk sewer to Valley View Road, the proposed alignment will extend through the I properties of 1868 County Road 83, 1870 County Road 83, 3300 Valley View Road, 2036 County Road 83 and the proposed River Valley Estates 2nd Addition, which is currently at the preliminary plat stage of the development process. I Both temporary and permanent easement acquisitions will be required as defined by the proposed project scope. Easements will need to be acquired for the properties of 1868 County I Road 83,1870 County Road 83, 3300 Valley View Road, 2036 County Road 83 and River Valley Estates and may require eminent domain proceedings. 3.1 Existing Conditions I 3.1.1 Roadway I The proposed project area runs along approximately 4,000 feet of CSAH 83 to Valley View Road. Through the entire project area, CSAH 83 is a two-lane, paved rural section highway. This project is not anticipated to impact the existing I roadway surface. 3.1.2 Sanitary Sewer I The existing sanitary sewer within the project area consists of 18-inch PVC pipe and was installed in 2004. This sanitary sewer trunk was extended to the south I plat line of the Church Addition with the construction of that subdivision. , The existing trunk is shown on Figure 2. This pipe has been sized to accommodate development in the southwest area of the City of Shakopee in accordance with the I City's Comprehensive Sewer Plan. An 18-inch PVC pipe was also installed under Valley View Road as part of the recent road improvements. The sewer extension project is proposed to connect to this pipe. I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shako pee, MN Page 1 WSB Project No. 1281-96 I I 3.1.3 Existing Property Owners The existing sanitary sewer line lies within the property of the Church Addition. I Properties to be impacted by the proposed installation of the trunk sanitary sewer line include: I . Shakopee Mdewakanton Sioux, PID 279-160-010 . Michael Hawkins, 1776 County Road 83, PID 279-160-120 ' . Harold & Roberta Schneider, 1870 County Road 83, PID 279-160-130 I . Harold & Roberta Schneider, 1868 County Road 83, PID 279-160-131 . Harold & Roberta Schneider, 3300 Valley View Road, PID 279-160..060 . Beverly Koehnen, 2036 County Road 83, PID 279-160-090 I . River Valley Estates, PID 273-870-300 I See the Appendix Figure 2 for the locations of the above properties. 3.1.4 Existing Utilities I Center Point Energy has an 8-inch.steel high pressure gas main that runs along the west side of CSAH 83 from CSAH 16 to approximately 1,000 feet south. This 8- I inch main then crosses CSAH 83 diagonally from the west to the ,east and continues east along the south plat line of the Church Addition. Where the 8-inch gas main crosses CSAH 83 a 2-inch plastic gas line extends to the south along the I west side of the CSAH 83 to approximately 35 feet south of the driveway to the 1868 CSAH 83 property. The 8-inch gas main is located north ofthe existing sanitary sewer manhole within the Church Addition and will not be crossed with I this project. The 2-inch gas line may require relocation or support when the proposed sanitary sewer is installed. I There are overhead power lines located on the east side of CSAH 83 that will likely require support during construction. This overhead power line runs north/south and has service lines crossing to west to serve the existing properties. I Fiber optic, telephone and cable television lines are also located on the east side of CSAH 83 at the north end of the project. At the north end of the project, these, utilities are located on the west edge of the proposed trench excavation limits and I will likely require relocation or support during construction. 4. PROPOSED IMPROVEMENTS I 4.1 Sanitary Sewer I The proposed project involves the construction of an IS-inch trunk sanitary sewer to be extended southerly along CSAH 83. The extension will begin at the existing trunk sanitary sewer near the southwestern corner of the Church Addition. The proposed pipe size and elevations are designed I to meet the capacity and depth requirements to serve the future development to the south by gravity sewer. See Figure 3 for the proposed pipe alignment. I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shako pee, MN Page 2 WSB Project No. 1281-96 I I The pipe alignment is proposed to extend through a primarily undeveloped area of the City. The area is currently zoned agricultural but is anticipated to be developed into residential and/or commercial areas in the future. The proposed sanitary line will connect to the existing 18-inch I trunk sanitary line at the south end of the Church Addition, and will extend approximately 400 feet to the south, then run to the southwest and cross beneath CSAH 83. The connection to the existing Church Addition sanitary sewer will be completed by core drilling the existing manhole. I The crossing beneath CSAH 83 is proposed to be installed by jacking since Scott County will not allow this road to be closed to traffic. The trunk sanitary sewer will extend to the south along the west side of CSAH 83 to Valley View Road. The portion of trunk sanitary sewer through the I River Valley Estates 2nd Addition development will be installed as part of that development's utility construction. I The land on the east side of CSAH 83 is owned by the Mdewakanton Sioux. The Mdewakanton Sioux have indicated their property could be served by a private sewer system and may not require public sanitary sewer service. Therefore, the sewer is proposed to pe constructed on the I east side of CSAH 83 for the initial 400 feet of the pipe extension and cross to the west side of CSAH 83 to serve the west side properties. The sewer is proposed to be placed on the east side for the first 400 feet to avoid impacting the property at 1776 CSAH 83 which has structures close I to the roadway. I The pipe construction proposed with the City's project terminates at the north plat line of the River Valley Estates 2nd Addition development. Further extension of this sanitary line will be constructed with of the River Valley Estates 2nd Addition utility construction. I At the north end of the proposed project the sewer depths are approximately 40 feet. The pipe shallows as it extends to the south to 25 feet deep at the north property line of2036 County Road I 83 and 15 feet deep at the north plat line of the River Valley Estates. Due to the depths of the sewer, it is proposed to use 18-inch diameter HOBAS pipe for this trunk sanitary sewer extension project. Hobas pipe is a specific manufactured brand of pipe that is a fiber glass I reinforced pipe and is designed for deep installations. It also provides the benefit of being virtually water tight and will minimize potential for groundwater infiltration. This type of pipe was recently used as part of Shakopee's River District Sanitary Sewer project. I Due to the significant depths required for the installation of this sewer and limited area for construction, this project will use special construction techniques. These techniques include I trench box construction and/or back casting to minimize the width of excavation to protect roadways, culverts, existing utilities and miscellaneous structures. The excavation width is also minimized to reduce the amount of temporary and permanent. easements to be acquired; and to I keep construction within existing right-of-way where no easements are proposed. This will increase construction costs due to the extra difficulty in construction using these techniques. The design of the alignment for the sanitary sewer kept the limits of the trench excavation a minimum I of IS-feet from the edge of driving lanes on CSAH 83. This may require temporary traffic barriers along the edge of CSAH 83 to protect the public from the deep excavations. A cross section of the design trench width used for the design of the trunk sanitary sewer alignment is I shown in Figure 4 in the Appendix. I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shakopee, MN Page 3 WSB Project No. 1281-96 I I The installation of the trunk sewer across the property at 2036 County Road 83 (Koehnen property) is proposed to be accomplished by one of two possible installation methods. The first installation method (Alternate 1) would be by open cut trench construction. This method would I involve clearing and grubbing the trees from the wooded area on this property and require a 40- foot-wide permanent easement and a 25-foot temporary construction easement. There would also be costs involved with the removal of all trees located within the proposed easements and I outside of CSAH 83 right-of-way. The second method of installation (Alternate 2) would be to directionally drill the trunk sanitary sewer using a HDPE pipe. This method would minimize the impact of construction on the property and would reduce the amount of easement area required. I CSAH 83 is proposed to be widened to a four-lane divided highway in the near future. The trunk sanitary sewer extension alignment must be located far enough away from the future roadway so I' the sewer can be maintained and repaired without disrupting traffic. This preliminary sewer alignment was designed considering the future roadway widening dimensions, but may be modified by Scott County in the plan review process. 1 4.2 Easement Acquisition I The proposed pipe will be crossing the properties of 1868 County Road 83, 1870 County Road 83,3300 Valley View Road, 2036 County Road 83, and the proposed River Valley Estates 2nd I Addition site. It is proposed to acquire an 80 to 40-foot-wide permanent utility easement for operating and maintaining the trunk sanitary sewer. An additional 40 to 25-foot-wide temporary easement on the west side of the permanent utility easement will also need to be acquired for the I sanitary sewer construction. See Figure 3 in the Appendix for the locations of these easements. It is anticipated that the eminent domain process will need to be utilized for the easement acquisition for the property at 2036 County Road 83 (Koehnen property). The use of directional I drilling or other trenchless technology for the construction across this property will eliminate the temporary easement. The eminent domain proceedings typically require at least 90 days before the City would be able to enter the property. The schedule established for this project provides I an allowance for this contingency. River Valley Estates 2nd Addition will provide the necessary easements for the trunk sanitary sewer with the final plat for this development. Due to the project schedule the construction limits, and therefore the easement width needs, have been I estimated using available soil data. Completion of on site borings are necessary to verify these assumptions. I 4.3 Permit Applications If it is the City Council's intent to move this project forwar4 into construction, the following I permits will need to be prepared and submitted on behalf of the City. It is anticipated that the City will provide fees for the submittals. I . Minnesota Pollution Control Agency/MCES - Sanitary Sewer Extension Permit . Scott County - Work within County right-of-way . Minnesota Pollution Control Agency - NPDES Phase II Construction Activity Permit I . DNR - Water Appropriations Permit for dewatering (if necessary) . NPDES Construction Activity Permit I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shako pee, MN Page 4 WSB Project No. 1281-96 I I 5. PROJECT COSTS A detailed cost estimate can be found in the Appendix. The following costs were prepared using I 2005 construction costs and are subject to change, depending on the final design of the project, bids received, and actual work performed. The total project costs, including construction and easement acquisition cQsts are estimated to be $894,718.75 for Alternate 1 and $901,331.25 for I Alternate 2. These costs include a 10% construction contingency and 25% indirect including engineering, legal, and administration costs for the project. I It should be noted this feasibility study addresses the extension of sewer from the Church Addition to Valley View Road, but the cost estimates for this trunk sanitary sewer only extend from the Church Addition to the north plat line of Ri ver Valley Estates. The portion of trunk I sanitary sewer from the north plat line of River Valley Estates to Valley View Road will be constructed with the utility construction of the River Valley Estates 2nd Addition. I 5.1 Sanitary Sewer The total project construction costs are estimated to be $676,843.75 for Alternate 1 and I $697,331.25 for Alternate 2. These costs include a 10% construction contingency and 25% indirect including engineering, legal.and administration costs for the project. Alternates 1 and 2 I are comparisons for installing the trunk sanitary sewer across the property at 2036 County Road 83 (Koehnen property) as discussed in Section 4.1 of this study. There are alsooversizing and overdepth costs associated with this project. Oversizing (and overdepth) costs are determined by I any costs associated with installing a sewer greater than an 8-inch line and typically at a depth of greater than 12 feet. The oversizing costs for this project are $488,867.50 for Alternate 1 and $509,355.00 for Alternate 2. See the Appendix for the detailed cost estimates for construction. I 5.2 Easement Acquisition I Permanent and temporary easements are required for the proposed sanitary sewer for its alignment through 1868 County Road 83, 1870 County Road 83,3300 Valley View Road, and 2036 County Road 83. The cost of the land acquisition and 25% indirect costs are necessary for I this project since there is insufficient right-of-way to install this sewer. The total easement acquisition cost for this project is estimated at $217,875.00 for Alternate 1 and $204,000.00 for Alternate 2. The land acquisition costs are based on an appraised value of the land for permanent I and temporary easement uses. See the Appendix for the detailed cost estimate for the easement acquisition. I 6. PROJECT FUNDING The funding source for this project will be the City's Sanitary Sewer Trunk Fund. Sources for I reimbursement of this fund include the River Valley Estates development and potentially adjacent properties that receive a lateral benefit. I I Feasibility Report CSAH 83 Sanitary Sewer Extension I City Project No. 2006-6 City of Shakopee, MN Page 5 WSB Project No. 1281-96 I I River Valley Estates Pulte Homes, the developer of River Valley Estates, will make a $150,000 contribution toward this project over and above all other assessments to their subdivision. Additionally, Pulte Homes I has agreed to contribute another $90,000 if the trunk sewer is in place for their use in September of 2006. If the trunk sewer is in place as planned Pulte Homes would not need to construct and operate a temporary lift station to serve their development. I Potential Lateral Sewer Connection Charges In addition to the proposed River Valley Estates development, this project could also benefit I undeveloped properties on the east and west side of CSAH 83 between the existing sewer and the new development. However, these connection charges would only be collected if and when the properties were developed. In order to determine the lateral connection charge, we first have to I remove any over-sizing and over-depth trunk costs. What will remain is a project cost based on a more typical8-inch main extension along the same alignment. These costs tot~ $194,051.26 including a temporary easement cost west of CSAH 83. The costs were then aIlocated to the east I and west sides of the improvement. The construction costs were equally allocated, the easement costs were assigned to the west side. As there are multiple property owners along the west side, a fair and equitable method of further allocating the costs had to be used. There are no I development plans or concepts for these properties but as the number of units that could be served in the future is directly related to the area of the parcels, the costs were allocated on an I acre basis. The resulting Lateral Sewer Connection Charge for this project is $1,465.91 per acre. The additional lateral computations are included in the Appendix.

The following schedule addresses the possible need to acquire the property through the use of eminent domain. I The proposed schedule outlines an aggressive program. However, the schedule for the eminent domain proceedings for 2036 County Road 83 will allow for work to commence as proposed with the construction across this property by late June. If eminent domain I proceedings become necessary for the Schneider parcel, construction will not be allowed to commence until late June, 2006.

CONCLUSIONS AND RECOMMENDATIONS Based on the preceding discussions we would offer the following conclusions: I 1. The construction of the project will require the acquisition of both permanent and . temporary easements across the Schneider, the Koehnen, and the proposed River Valley I Estates properties. 2. The project funding will utilize City Sanitary Sewer Trunk Funds for the pipe extension I from the existing Church Addition sanitary sewer line to the north edge of the River Valley Estates property. Fund reimbursement sources include River Valley Estates contributions and Lateral Sewer Connection Charges. I 3. The River Valley Estates Development is willing to pay an additional $90,000 towards the construction of this trunk sanitary sewer if the system is operational in September, . I 2006 for the development's connection to the sewer. 4. Itis anticipated that eminent domain proceedings will be necessary to acquire the I permanent easements across at least one parcel in the project corridor for the construction of the project. I 5. This project is being completed as a Chapter 429 Improvement. This process will require a public hearing for the project and the Council will need to order the improvement following the hearing in order to proceed. I 6. The project as proposed is necessary, feasible and cost effective from an engineering I standpoint. Based on the conclusions listed, the following is recommended: I 1. It is recommended that Alternate 2 (directional drill) be used to cross 2036 County Road 83 (Koehnen property). This will allow the City to avoid and minimize easement and I construction costs required to cross the property compared to the costs of the sewer being installed by open cut trench method. I 2. It is recommended that the City Council accept the feasibility report as presented and call for the public hearing. I 3. The City Council initiate the easement acquisition process (eminent domain if necessary) in accordance with the schedule as proposed herein. This will allow the City to realize the process necessary for easement acquisition at the time of the public hearing.
